Abstract
Using the181Ta(n, γ) and141Pr(n, γ) reactions to provide a dense series of intenseγ-rays, photoexcitation of the238U nucleus has been studied in the 4–7 MeV range. It is shown that most of the effective cross sections are in line with an average strength function as given by the GDR Lorentzian line superimposed by Porter-Thomas fluctuations. Resonances of nonstatistical strength are found close to 5.2 MeV.
